Waterproofing implies applying a thick waterproof layer to the surface of the building structures and commercial/residential facilities to ensure thorough protection from water and corrosive liquids. Waterproofing boosts efficient operation of buildings, structures and equipment, increases their reliability and useful life.

From a functional point of reference there are two types of waterproofing to be defined: anti filtration one, designed for protection against the ingress of water into the underground and underwater structures, leakages of the operating, technical or waste water; and corrosion waterproofing that aims at protecting structures from chemically aggressive liquids and water, the harmful effects of the atmosphere.

By structural features waterproofing is divided into superficial, that aims at reinforcing structure interfaces, and multi-purpose one. By the type of material used, waterproofing is divided into asphalt, mineral, metal and plastic types.

By the method of waterproofing is subdivided into:

Paint waterproofing (hot and cold) is performed in the form of a thin, 2 mm multilayer coating commonly bituminous and polymeric coatings and paints for corrosion and anti-capillary protection of concrete and metal structures. The method is utilised in roof coating and roof waterproofing.

Backlining waterproofing, where roll materials produced as multilayers (and typically comprised of 3-4 layers) with mandatory protection coating surface and the wall ties.

Cast waterproofing, usually produced from a hot mix of asphalt mastic and casting. The solution is applied on horizontal bases (2-3 layers with an average thickness of 20 -25mm), filled to the walls or on the walls’ formworks (30 – 50mm thickness).

The Benefits Of Anticorrosive Paints Revealed

To provide protection against corrosion of reinforced concrete and steel structures, equipment, bridges, pipelines and storage tanks, one can resort to moisture-curing polyurethane systems. The innovative products, supplied to the market by seasoned players, such as Britannia Company, specialising in mass production of roof waterproofing and roof coating materials, provide unique properties that allow applying anti-corrosion coatings in the extreme conditions:

Ultrasonic cleaning – method of cleaning the surface from solid and liquid contaminants is based on the excitation of ultrasonic frequency in the washing solution. The scientific basis for the creation and development of technology equipment ultrasonic cleaning laid in the field of acoustic cavitation conducted at the Acoustics Institute named after Academician Andreeva led by Professor Rosenberg.

Ultrasonic cleaning can replace manual labor, thereby speeding up the cleaning process, a high degree of surface smoothness virtually eliminate the use of inflammable and toxic solvents. Thus, according to Hilsonic statistics (the company is focusing its efforts on producing ultrasound equipment and ultrasonic cleaner models in particular) reports that despite the higher energy consumption and relatively high maintenance costs, its customers managed to cut down operational expenses by 18% on average.

Ultrasonic cleaning process provides its effect due to several phenomena that occur in the field of high intensity of ultrasound: acoustic cavitation, acoustic currents, radiation pressure and acoustic-capillary pressure.

Depending on the type of contamination, the predominant role is played by various purification processes. Thus, the destruction of contaminants occurs weakly interrelated, mainly under the influence of pulsating cavitation bubbles. On the edges of the film contamination pulsating bubbles, making intense vibrations, overcoming the cohesive forces of the film to the surface, penetrating the film and breaking it. Radiation pressure and acoustocapillary effect contribute to the penetration of cleaning solution in the micropores, bumps and blind channels. Acoustic flow is accelerated removal of dirt from the surface. If contamination is firmly connected to the surface, its elimination requires collapsing cavitation bubbles, creating a microshock impact to the surface.

Basically gantry hoists are used to move lengthy and bulky objects and typically taken advantage of at industrial warehouses of large area or open construction sites. Gantry hoist construction is in demand in hangars and workshops of enterprises engaged in production of concrete products, freight yards. In addition, the cranes are widely used to perform a variety of cargo handling, lifting and installation works on container platforms of railway junctions. One of the most mature and seasoned overhead cranes and gantry hoist UK manufacturers is Granada Material Handling, producing the equipment at industrial scales for both local and abroad markets.

Design features

A true to type gantry crane consists of a single-girder or double-girder bridge (without brackets and one or two consoles), two metal poles and moving hoist or trolley. The construction, depending on the modification of the crane, may also include a variety of lifting devices: grab, magnetic disk, and numerous specialised units and elements.

Gantry crane is controlled from the operator’s cab or from the ground through the keypad station. You can control the crane remotely via radio control console. In standard climatic design gantry cranes can be operated in the range of -20 to + 40 ° C; the low temperature constructions operate within the range from -40 to + 40°C.

Definitely, apart from way more moderate energy consumption appetites, there is plenty of reasons to switch to LED lighting. The article aims at educating both general public as well as business oriented individuals looking to take advantage of the brand-new technology. The benefits described in the article have been successfully turned into account by Metcraft Lighting manufacturers, a seasoned UK-based business focused on commercial led street lights production.

LED lamps were initially used only in very specific purposes (largely as indicators on the instrument panels); now LED technology and LED lighting systems have penetrated almost every market area, marching successfully throughout the globe, replacing the traditional incandescent and fluorescent lamps.

Smart lighting systems

LED technology (LED) is far superior to all other options of programmable indoors and outdoors lighting. In essence, LED lighting is ideal for use in devices that require controls light intensity (dimmers), volume sensors, timers, and so on. Unlike other light sources, the LEDs provide an ability to change the intensity of light and in addition to energy savings, help to increase the life of LEDs. Furthermore, the LEDs may operate continuously without detriment to their effectiveness and functioning.

Lighting features allow the creation of innovative models

LED lighting system (LED) provide a very directional light beam patterns and regular uniform brightness in outdoor and outdoor spaces. LEDs produce neither glare nor strobe effects. Their use offers great opportunities for innovative design to create luminaires of maximum efficiency lighting systems due to its small size and variety of forms. Furthermore, since LEDs are monochromatic light sources, they don’t give infrared or ultraviolet radiation; emitting high saturation colors they are even brighter than conventional lamps.

Instant start

Unlike fluorescent (energy saving) or sodium vapor lamps, LEDs start generating light instantly, achieving an optimum level of brightness and color temperature (even at temperatures down to -30ºC) in milliseconds. Thus, an additional benefits is a production of a shimmering effect: a nonsignificant at first sight opportunity contributed to the emergence of the entire industry of live shows lighting.

No harmful effects on the historical monuments and wildlife

Since LED lamps provide very little heat and do not emit infrared and ultraviolet rays, they can be used for lighting of historical buildings and living plants without no risk of damaging. The technology has successfully been integrated in zoo and reservations.

Environmental protection

LED lamps can be recycled quite easily, so they don’t contribute to environment pollution. Energy-saving fluorescent lamps and sodium lamps contain mercury; moreover, fluorescent lamps emit electromagnetic waves that are harmful to health when used near human (e.g. as a table lamp or lamps on the bedside tables).

In addition LED lighting manufacturing demands less copper cable due to a tiny diameter of the copper cable in the LED design (it is much smaller than the diameter of the cable of the traditional sodium or metal halide lamps). Therefore, due to copper cost reduction, significant savings can be achieved.

Every year UK government allocates about two billion pounds (about 3.2 billion) on legal aid; half of the amount goes to criminal cases, another half to civilian ones. The Ministry of Justice is expected to reduce the appropriation to 215 million pounds ($344 million). Under the plan, the salary of lawyers in complex and expensive affairs should be decreases by 30%, in the rest – by 18%. In criminal cases the contracts will be distributed through the tender, which is likely to be won by those offering the lowest costs. As a consequence, the defendants will not be able to choose a legal representative.

Probation legal adjustments

In the field of probation a number of changes has also been implemented. General Secretary of the National Association of Inspectors Jan Lawrence criticized the project of the Ministry. ‘The government’s plan to transfer 70% of inspection to private owners is rash and untested – he says. ‘It’s a dangerous social experiment that will lead to reductions in the area of rehabilitation and the risk of collapse of the control system, which would create a danger to society’.

Ministry of Justice plans to raise concerns and grievances and lawyers. Nicola Hill, president of the Association of London Criminal Courts Solicitors, is convinced that the desire of minister to save on legal aid system can lead to disaster. ‘The risk that the innocent may go to jail, the nightmare may become reality’, – warns Hill. ‘The number of cases of injustice in common people will increase, because the citizens won’t be able to get a decent lawyer’. Matt Foot of Justice of the Commonwealth has the same opinion: ‘Because of the cuts [appropriations], all but the rich will suffer, so we decided to unite and fight back’.

London solicitors association measures, which is the government do not seem forced. The Association believes that they cause serious damage to the criminal justice system, because qualified and experienced lawyers will leave their job, paid from the state budget, and will be looking for more profitable places. According to forecasts of the association, many law firms will quickly go to the bottom, while professionals will be replaced by less skilled employees and, accordingly, not such costly.

Among the lawyers supporting the union of human rights, defenders and civil society are such groups as Liberty, Unite, The Howard League for Penal Reform, Coram Children’s Legal Centre. A charitable organization Children’s Society drew attention to the fact that the blow will be delivered to children, and legal aid will not be available to ‘the most vulnerable population group’ including those who suffer from domestic violence. ‘If people are not able to consult with a lawyer due to the fact that more and more law firms are closed’, says the head of the organization Gillian Guy, ‘then the catastrophic effects of innovations will affect not only those who are indicted, but the whole society’. Human rights organizations have expressed the view that the planned changes will undermine the international prestige of the entire judicial system of Great Britain.
